Descriptive Notes on Papuan Planis. 
flowers, more numeroTis stamens, broader capsule and much broader 
seeds, which latter however are arranged like those of T. macrosperma. 
T. rufescens (Hance in Trimen’s Journal of Bot. 187b, p. 259) from 
Cambqja is easily distinguished by its vestiture and fewer stamens. The 
New Caledonian species, as far as known to me, namely T. Guillamii 
(Veil!. Coll. 2221), T. Callobuxus (Benth. et Hook. Gen. PI. i. 709), 
T. glauca (Brogn. et Gris ; Panch. n. 70, Veill. n. 907), T. capitulata 
(Panch. in Annal. des Scienc. Nat. ser. cinq. ii. 130) and T. Veillardii 
(Brogn. et Gris 5 Veill. 2179) are all except the one last mentioned very 
distinct from the Papuan species; T. Veillardii differs however in 
blunt leaves somewhat decurrent into the petiole, in smaller flowers, 
obtuse lobes of the calyx, stamens not exceeding the petals and perhaps 
its fruit, which I have not seen. T. Burmanica (Griff. Plant. Cantor, 
49) is not available to me for comparison. 
It may be here incidentally remarked, that the Melaleuca pungens of 
Brogn. et Gris, 1. c. 139, has to change its specific name, which is pre- 
occupied by a West- Australian plant (Schauer in Lchm. PI. Preiss. i- 
138) ; the New Caledonian species might be named 31, Brogniartii in 
memory of the great savant, who recently passed away from his luminous 
career, and who so largely elucidated the New Caledonian vegetation. 
That the length of the stamens is not of absolute generic value in 
Myrtaceas became demonstrated by the extreme shortness of the fila- 
ments of some species of Tristania and also of Eucalyptus and other 
cognate genera ; hence it is advisable to transfer all the Cloezias to 
Metrosideros. In the latter genus occur species with a five-celled 
ovary. 
Myrtella. 
Lohes of the calyx 5, almost vahate before expansion, not scarious, 
as long or somewhat shorter than the petals. Stamens uniseriate,free, 
about 30, scarcely longer than the lobes of the calyx. Cells of the 
anthers slit longitudinally. Style short. Stigma very minute. Ovary 
three-celled', ovules few or several in each cell, aflixed to the axillary 
placentas. Fruit unknown. Papuan shrubs with small oppo>site leaves, 
axillary solitary small flowers and long - persistent bracteoles. Tlie 
absence of ripe fruits renilers it impossible to designate even the tribe of 
Myrtacem. into which this genus should be placed, whether Bmckeacete 
or Myrtca^; meanwhile the characteristics of the genus rest mainly on 
the nearly valvular proflorescence of the calyx.
